Introduction of Problem Domain and Dataset

This project is about the vaccinations of COVID-19 vaccines in the US. Given that the Delta variant is causing a new surge of COVID-19 cases, it is key that all people get their vaccination as soon as possible. We are eager to know how people of different states react to vaccination. By breaking down the vaccinated population by state, it would be easier to create targeting incentives, promoting vaccination to fight against the more transmissible Delta variant. Our data set is downloaded from the CDC website and contains information including the amount of vaccines distributed to and administered in each state over the course of 228 days, from 12/20/2020 to 08/04/2021.

We sorted the table in descending order based on the Percentage of Daily Vaccinated Population, and Vermont tuned out to be the state with the most percentage of population vaccinated every day. This result resonates well with one of the conclusion we drew from the summary: Vermont has the highest fully-vaccinated population ratio among all states.

We were also interested in knowing on what day in the week people are the most willing to go get vaccinated in the week and concluded from that Saturday has the most vaccinations; this is likely because many people work on weekdays and are not able to go get their vaccination on such days. Another thing we found interesting from the table is that the states with higher rates of fully vaccinated population are democratic states.

Leaflet Map

Below is a map that shows the percentage of the population that is fully vaccinated in each state.

We used Leaflet, the most common open source for interactive map charts, to generate the map and facilitate further web-page programming using shiny(). While there are other districts, departments, and entities listed in the data, we only selected the 51 states/districts in the US as we hoped to see the distribution of the fully vaccinated population in each states. Based on the map, we are able to conclude that states on the west coast and the upper east coast are the most vaccinated states, while many of the southern states are the least vaccinated states. This result can be tied back to the aggregated table and illustrate the fact that democratic states tend to have the highest rate of vaccinated population.

Area Graph

Below is a area graph that shows the trend of vaccinations in weeks starting from week 1 in 2021 to week 31 in 2021 (01/04/2012 - 08/04/2021). *Note that week 31 only has data for three days.

We used an area chart for our data set with a great scale of quantitative data, as it is one of the best way for communicating a trend over the course of a specified period.

The area graph shows that the weekly vaccination in the US in 2021 started at around 4 million at the beginning and increased until it peaked in week 15, which is mid-April. However, the number of weekly vaccinations started to decrease afterwards. The reason why this sudden and sharp decline is yet to be discussed and will be included in the final submission.

Bar Chart

Below is a bar chart that shows the percentage of males and females in the US population, the vaccinated population, and the people vaccinated in the last 14 days.

Bar chart is a useful layout to compare the differences between genders in our data set. According the the three bars shown above, while the percentage of females and males in the US are nearly equal, more females are vaccinated than males in the fully-vaccinated population. At this point in time, we can conclude that females are generally more open to vaccination than males in the US.
